Abstract: 본 발명은 흡기누설을 측정하고 및 판단하기 위한 흡기누설 감지방법을 LPEGR 시스템에 적용하여, 흡기계의 누설을 조기진단하고 판단하여, 운전자에게 정비가 필요함을 알림으로서, LPEGR이 장착된 터보차져 및 엔진을 보호하며, 특히 누설위치에 따라 누설 유형이 다름을 고려하여 서로 다른 해결로직을 제시하고자 한다. 엔진 흡기계에 누설이 발생되면 터보챠저 전단에서 측정되는 공기량과 엔지에 흡입되는 공기량의 차이가 발생하게 되어 공연비가 차이가 나고, 이 공연비와 배기 람다값의 차이를 비교하여 기 지정된 값 이상의 차이가 발생하면 흡기 누설로 판단하고, 정비가 필요함을 운전자에게 알리며 특히, 누설위치에 따라 누설 유형이 다름을 고려하여 서로 다른 로직을 적용하여 판단한다. 누설유형 별로 누설이 확정되게 되면, 누설사실을 운전자에게 시각신호나 청각신호로 경고하거나, EGR의 작동을 중지하거나 통제하거나, 엔진 토크리미티를 작동시켜 터보챠져 및 엔진의 손상을 방지한다.

Abstract: PURPOSE: A vane control method of a turbo charger is provided to prevent the rotation speed of a turbine and the boost pressure from being excessively increased during repetitively accelerated driving. CONSTITUTION: A vane control method of a turbocharger is as follows. An acceleration counter and a timer are initialized, and the timer is operated. A value of the acceleration counter is increased in case both of the degree of opening of an accelerator and a differential value of the degree of opening of the accelerator pedal are equal to predetermined values. Repetitive acceleration is determined when the timer shows that the time is less than a fixed time, and when the value of the acceleration counter is more than a predetermined acceleration value. A vane control value is compensated to open a vane as much as the predetermined value in case of repetitive acceleration.
